Abstract

PURPOSE: To enhance the starting characteristic by gasifying the liquid fuel, mixing with air, and controlling the fuel injection start timing according to whether the combustion chamber temp. of an engine to make spark ignition is higher or lower than the specified value.
CONSTITUTION: An electronic control device CPU 6 reads signals from an ignition switch 11, starter switch(SS) 12, and a temp. sensor 13. In accordance with the inflammation point of the fuel used and the temp. of the combustion chamber, the CPU 6 controls drive of a fuel injection valve 15 by reference to a control table 18 in which the injection start timing has been set. When the combustion chamber temp. is higher than the specific value, the injection valve 15 is driven at the same time as turning-on of a starter switch 12 so as to start the fuel injection. At the time of low temp., a throttle valve 16 is opened either fully or to the half depending upon the temp. when the starter switch 12 is turned on, and thus the compression ratio is enlarged, and the combustion chamber is heated. When the time set on a timer 14 is up, the fuel injection valve 15 is opened to make fuel injection. Thereby the low temp. starting characteristic is enhanced even with a fuel having a high inflammation point.
